What Is the Mainstay Funds Income Tax Information Notice 2024?

The MainStay Funds income tax information notice 2024 is a tax document issued to investors who hold shares in MainStay mutual funds or related investment funds.

This notice contains important tax information about the income you earned from your investments during the year 2024.

It helps you understand:

  • How much income you receive?
  • What part is taxable
  • What part is tax-free
  • Whether any amount is return of capital
  • If AMT applies to you
  • How to report this in your tax return

In short, it tells you exactly how your fund income should be treated for tax purposes.


When Will You Receive This Tax Notice?

MainStay Funds will issue 2024 tax information, including Form 1099-DIV, by February 2025.

This means:

  • You will usually receive it in January or February 2025
  • It may arrive by mail or electronically
  • It will be available in your investor account

If you are waiting for this document before filing your return, don’t worry. This timeline is normal.

Never file your taxes using estimates if this form is still pending.


What Is Form 1099-DIV, and Why Is It Important?

One of the main documents included in this notice is Form 1099-DIV.

This form shows the income you earned from your fund investments.

It includes details such as:

  • Ordinary dividends
  • Qualified dividends
  • Capital gain distributions
  • Non-dividend distributions
  • Federal tax withheld 

This form is essential for filing your return.

Without it, your tax filing may be incomplete or incorrect.


Understanding MainStay Tax Information in Simple Words

The MainStay tax information section of the notice explains how your fund income is categorized.

Not all money you receive from funds is treated the same way for tax purposes.

Some parts are taxable. Some parts are not.


Taxable and Non-Taxable Distributions

Your fund may give you different types of distributions.

1. Taxable Distributions

These are fully taxable and must be reported in your return.

They include:

  • Regular dividends
  • Capital gains
  • Interest income

These increase your tax liability.

2. Non-Taxable Distributions

These are not taxed immediately.

They may include:

  • Return of capital
  • Certain municipal bond income

Even though they are not taxed now, they still affect your future taxes.

That’s why tracking them is important.


What Is Return of Capital and Why It Matters

One term that confuses many investors is return of capital.

It sounds like income, but it’s actually different.

Return of capital means:

The fund is giving you back part of your original investment.

It is not profit.

So:

  • It is usually not taxed immediately
  • It reduces your investment cost
  • It affects future capital gains

If you ignore this part, you may pay more tax later.

That’s why this section of the fund tax notice is very important.


Special Note for Municipal Fund Investors

If you invest in municipal funds, this notice is even more important for you.

Shareholders, particularly of municipal funds, should look for:

  • State-specific tax-exempt interest percentages
  • Alternative Minimum Tax (AMT) information

Some municipal income is tax-free at the federal level but taxable at the state level.

Some income may trigger AMT.

Your notice explains all this in detail.

Always check this section carefully.


What Is AMT and Why Should You Care?

AMT stands for Alternative Minimum Tax.

It is a separate tax system designed to ensure high-income taxpayers pay minimum tax.

Some fund income may be subject to AMT.

If your notice mentions AMT income, it means:

  • You may need extra calculations
  • Your tax software must consider this
  • Your tax liability may change

Ignoring AMT information can lead to underreporting.


What Information Does the Fund Tax Notice Contain?

Your fund tax notice usually includes:

  • Total distributions
  • Taxable income
  • Tax-free income
  • Return of capital
  • Capital gains
  • AMT-related income
  • State-level details
  • Federal reporting figures

All this information is structured to match tax return forms.

It is meant to make filing easier, not harder.


How Shareholders Should Use This Tax Notice

If you are a shareholder, this document is your tax roadmap.

Here’s how to use it properly.

Step 1: Collect All Tax Documents

Before filing, gather:

  • MainStay tax notice
  • Form 1099-DIV
  • Bank interest statements
  • Other investment reports

Keep everything together.

Step 2: Match With Your Records

Compare the notice with:

  • Your account statements
  • Dividend records
  • Distribution history

If something looks wrong, contact support immediately.

Step 3: Enter Details in Your Return

Use the numbers exactly as given.

Do not round off randomly.

Do not estimate.

Accuracy matters.

Step 4: Check State-Specific Information

If you live in a state with special tax rules, pay close attention to this section.

It can save you money.


Common Mistakes Investors Make

Many people lose money or get notices because of small mistakes.

Avoid these:

  • Filing before receiving the notice
  • Ignoring return of capital
  • Skipping AMT information
  • Using old data
  • Missing state details
  • Not reporting all income

These errors can trigger audits or penalties.


Why This Notice Is More Important Than You Think

Many investors treat tax notices casually.

That’s a big mistake.

This document helps you:

  • Avoid overpaying tax
  • Avoid underreporting
  • Prevent future disputes
  • Maintain clean records
  • Protect your investments

A few minutes of careful reading can save you years of trouble.


What If You Have Not Received the Notice?

If February is over and you still haven’t received it:

  • Check your online account
  • Check your email spam folder
  • Contact customer support
  • Verify your address

Never file without it unless advised by a professional.


Should You File Taxes Without This Notice?

In most cases, no.

Waiting is better than filing incorrectly.

Filing with wrong data can lead to:

  • Revised returns
  • Penalties
  • Interest
  • Scrutiny

Patience here pays off.
